I fly weekly and thankfully take advantage of 'Fast Track' in the airport - I choose the Mid Stay location as this is cost-effective, often easier/quicker to find a parking space than Short Stay due to demand and only a very short 2-3 min walk from the carpark to the newer 'Fast Track' side entrance at the Airport. The online booking service is fairly straightforward, but slightly cumbersome down to the number of clicks. Also slightly frustrating you can't add multiple parking requirements / dates into a 'basket' to process a total payment in one go, as adding these seperately when booking 3-4 weeks of travel can be labourious.
